Tomei TA304A-MT01A Valve Springs for Mitsubishi 4G63

The Tomei TA304A-MT01A valve springs are engineered specifically for the Mitsubishi 4G63 engine, a stalwart in the world of performance tuning. With a legacy that dates back to 1968, Tomei has consistently delivered high-quality components that meet the rigorous demands of motorsport and high-performance applications.

Material and Construction

These valve springs are constructed from oil-tempered chromium-silicone alloy steel wire, recognized as the industry standard for performance springs. This material choice ensures excellent durability and resistance to fatigue, making it ideal for engines that operate at high RPMs. The springs also undergo a nitrogen surface treatment, which enhances their fatigue limit and improves compression repulsion, critical for maintaining valve control under extreme conditions.

Performance Features

  • Increased Fatigue Limit: The combination of high-quality materials and advanced surface treatment provides a 1.5 times increase in fatigue limit, significantly reducing the risk of spring failure even at 10,000 RPM.
  • Optimized Design: The design minimizes valve bounce and jump, ensuring precise camshaft movement transfer, which is essential for high-performance setups.
  • High Lift Compatibility: These springs are designed to handle high lift camshafts, making them suitable for aggressive engine builds.

Installation Notes

For detailed installation instructions, refer to the official Tomei documentation available here. Proper installation is crucial to ensure optimal performance and longevity of the springs.
